SEB AND POLISHER.

Application led June 27, 1921. Serial No. 4840,569.

To all whom t may concern:

Be it known that I, WILLIAM SEvEnNs, a citizen of the United States, anda resident of the city of Chicago, in the .county of Cook and State ofIllinois, have invented certain new and useful Improvements in a Sanderand Polisher; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawings, and to the numerals of reference marked thereon,which form a part of this speciication.

This invention relates to improvements in Sanders and polishers for oorsor the like and has for one of its objects the provision of such anapparatus which can be readily manipulated and to which the polishingmeans or sanding means such as a cloth, sand paper, or the like, may beapplied, and on which said surfacing means will be very securely held inposition.

An objrct of this invention is the provision of a sander and polisherwhich is adapted to be pushed about on a ioor by means of a handlefitted thereinto by a exibly mounted socket and which sander shall havesuiiicient weight so that any undue pressure thereon is not required.

A further important object of this invention is the provision of asander or polisher having means thereon adapted to securely clamp andhold in position any polishing or abrasive means and which shall so holdthe sanding or polishing means that it will be impossible for the sameto work loose while in use.

A still further important object of the invention is the provision of asanding and polishing means provided with a tensioned clamping meanswhich is' adjustable.

Still another important object of the invention is the p-rovision of asanding and polishing apparatus provided with a clamping meansconsisting of a spring plate or the like cooperating with the base ofthe holder in such a manner as to securely hold any thickness of sandingor polishing means thereon no matter in what position. and to hold thesame without any danger of its becomin loose during use.

`Other an further important objects of this invention will be apparentfrom the disclosures in the accompanying drawings and followingspecification.

The invention (in. a preferred form) is illustrated in thc drawings andhereinafter more fully described.

0n the drawings:

Figure l is a top plan View of the improved polishing and sandingapparatus, with the handle removed therefrom.

Figure 2 is a section taken on the line 2 2 of Figure 1 looking in thedirection indicated by the arrows.

Figure 3 is a section taken approximately on the line 3 3 of Figure 1.

Figure 4 is a sectional view' showing the apparatus before thetensioning means has been adjusted to .holding position.

Figure 5 is a side elevation of the sander and polisher assembled andwith the handle applied thereto.

As shown on the drawings The apparatus comprises a base 10 of any hardand heavy material such as a suitable metal of a desired thickness andhaving an npstanding flange 12 therearound encircling all the sidesthereof. This base 10 is preferably of a rectangular form as shown.Adapted to cooperate with the base by means of an attachment to anupwardly extending integral lug 14 in the middle thereof is a socketmember 1G pivoted thereto by means of a bolt or rivet 18 passing througha hole in the lug 14 and this socket 16 is adapted to be swung aboutsaid pivot for the accommodation and manipulation of a handle 20 whichis provided with screw threads or other means on the end thereof forsuitable cooperation with the socket 16. Fitted in the bottom of thebase 10' and having their heads 24 set in depressions therein are theupwardly extending threaded bolts 22 provided with lock nuts 26 coactingwith the upper face of the base 10'to hold the bolts in position. Thesebolts 22 are provided with screw threads and have winged nuts 28 mountedthereon adapted to cooperate with and hold in position a exible springplate 30 formed preferably in the shape of a circular arc as shown inFigures 3 and 4 and made of such material that it may be subjected totension. The edges of this arc-sha ed tension member or plate 30 areAstraig t and adapted to contact with the top of the base 10, or with/theinner face of the anges 12 on two opposite sides thereof near thejunction of these faces and aber? the top. This junction forms theinterior of an angle which acts like a groove to cooperate with the edgeof the sprin and cause the covering 32 to be tighten upon turnin downthe nuts 28. This covering 32 which is of sand paper, polishing cloth orthe like is thus securely held in position.

The o eration is as follows:

The p ate member 30 is lifted from the base 10 by unscrewing the wingednuts 28 on the bolts 22 and then a piece of polishing cloth, sand paper,or the like, as shown at 32, is placed in posit-ion upon the basepassing thereunder and with its ends overlapping the upper edges of theupwardly extending flange 12 on two sides of the apparatus. The plate 30is then placed in position as shown in Figure 4 with the polishing clothor sand paper 32 drawn as tightly as possible. After this the win ednuts 28 are tightened, thereby tensioning the plate 30 and causing itsstraight sides or edges to push the Vpolishing member or sand pa er 32very closely into the angles formed etween the base 10 and itsupstanding anges 12 as shown in Figure 3, securely holding the same inposition and affording a very accurate contact between the bottom of thebase. 10 and the polisher 32. The apparatus is then ready for use andcan be used in connection lwith almost any material to be polished, asioors, furniture or the like, the size of the polisher. being of coursevariable to suit the particular requirements. lIts weight is such thatno undue pressure will be needed to polish a :floor or the like, thepressure necessary to push the body over the surface of the articlebeing polished usually being found entirely suicient.

It will be evident that the polishin member or cloth 32 may be readilycanged whenever desired and with a mmimum of' time and inconvenience andthat when laced in position it will be very securely lield and cannotbecome loose through the operation of the polisher.

Leoni It willfurther be evident that when this device is used as apolishing means with a polishing cloth or the like 32 u on the bottomthereof, a quantity of liqui polish may be placed in the base or asuitable container therein and allowed to penetrate to the polishing1cloth 32 through the openings around t e bolts 22 or other small oenings which may be made through the ase 10 if desired.

The shape of the polisher may bevaried as desired, a triangular,circular or other form of base being readily adaptable to the invention.The winged nuts may further be substituted by any suitable clampingmeans, and the bolts coactin therewith may be made integral with the aseif preferred.

I am aware that man changes may be made and various detai s ofconstruction varied without departin from the principles of thisinvention, .an I therefore do not purpose limiting the patent grantedthereon otherwise than necessitated by the prior art.

I claim as my invention:

A floor polishing device, com rising a base formed with an upstandingange and a central inte al lug, an arc-sha ed spring plate, threadedbolts fixed to said base and at their up er ends assing throughapertures in sai spring p ate, wing nuts on Said bolts adapted to engagethe up r surfaces of said spring plate to flatten t e same and to grip afinishing material between the plate ed es and the inner facesbf theflange on said ase, and a handle-receiving socket pivoted to the centrallu projecting freely throug said spring plate.

In testimony whereof I have hereunto subscribed my name in the presenceof two subscribing witnesses.

LIAM SEVERNS.
